Manufacturing Quality Control of STILBENE YELLOW
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dye Content) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in 1% aqueous solution. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals after acid digestion by measuring element-specific emission spectra. |
| Chloride Ion | Argentometric Titration | Determines chloride concentration by titration with silver nitrate using potassium chromate indicator. |
| Sulfate Content | Gravimetric Analysis (as BaSO4) | Precipitates sulfate as barium sulfate and determines mass after filtration and drying. |
| Water Solubility | Visual Inspection and Filtration | Evaluates complete dissolution in specified water volume at defined temperature and time. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of sample solution to certified reference standard under identical conditions. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies impurities using reversed-phase chromatography with UV detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder by analyzing angular scattering pattern of laser beam. |
| Bulk Density | Gravimetric Volumetric Method | Calculates mass per unit volume of material poured into a standardized cylinder under controlled conditions. |
